Next to the small station, this room itself is arranged as a base station, at this time has been arranged into a place similar to a radio war room, 20 people are nervously sending and receiving radio signals, the straight-line distance of the entire railway is 50 kilometers, but the two ends of the railway, plus the small station in the middle, have been arranged for the first time on the base station, this kind of base station produced by the industry is enough to ensure communication within a radius of 25 kilometers.

The 20 radio stations here are guaranteed to be able to communicate with the 12 pre-arranged points anytime and anywhere. This is also the first application of telegraph in train speed measurement, 50 kilometers of distance, there are at least 12 nodes, used to carry out a systematic speed measurement of the full speed of the train, each node is a little more than 4 kilometers, these nodes, responsible for mastering 5-10 different speed measurement points, will be the train passage of the precise time, summarized to the node, and then through the radio of the 12 nodes, for reporting.

This information, through the guò wireless telegraphy, was gathered into this small radio room, the telegraph operator listened to the radio signals, and then reported one by one, after every point was connected, the next thing was to wait for the train to pass guò, and this preliminary preparation has been completely completed.

50 kilometers of distance, according to the average speed of 100 kilometers per hour, under the safety of the situation, at most half an hour, the train will go through this test journey, this is destined to be a very short time, the first time the high-speed train runs on the land of China, will inevitably open a new history.

All kinds of numbers, to summarize them all, it will take time, these are not in a hurry. In this radio room, there is no electronic large screen of later generations, but a huge blackboard is set up in the center, on the blackboard, you can pass guò chalk, divide the area of 50 kilometers, intuitive description, at this time, only a few minutes, the train has not been raised to the highest speed, the train has not yet entered the first node, so, including Yang Yuanzhao, many observers, are quietly waiting, about 5 minutes later, the telegram of the first node came, and the telegraph operator burst out the numbers in an instant, at 9:34 a.m., the first node of Tongguò.

nodes, that is, where the radio transceiver is placed, they will record the time with a stopwatch at the first time when the train passes through guò, including the end point www.biquge.info the pen fun pavilion, 13 stopwatches are copied with the help of an all-in-one machine, watches from later generations, even if they are ordinary, the accuracy is more accurate than this era, and it is best to record time.

The time transmitted from the telegraph was 9:34 seconds32, and the time when the train left the station just now was 9:30 sharp, that is, about 4 and a half minutes, when the first node was reached, except for the initial acceleration, the speed at which the train should have traveled through Guò was not slow.

Yang Yuanzhao's brows furrowed slightly, this kind of acceleration is not something he wants to see, it should be Zhan Tianyou's request on the train, this stubborn engineer can't be obedient.

There is also a telegraph on the train, and the two train drivers have undergone simple training, and they can transmit some information through the transmitter on a fixed basis, and they can also accept some fixed instructions.

Yang Yuanzhao thought about it for a while, but still didn't give an order, not to mention whether the order given would be accepted, even if it was accepted, the train was also a mechanical object, and it would run at a fixed speed, and there would not be too many problems, but once it was changed, it would be easy to have problems.

Zhan Tianyou is very important to Baotou, especially on the railway, the importance is even more than Yang Yuanzhao's storage zài, under normal circumstances, Yang Yuanzhao will not let him take risks, but he is very confident in the steam engine he modified, and the higher speed of the all-in-one machine has been tested, so it is regarded as a special real yàn.

In the whole room, in addition to the unique sound of the radio transceiver, there was only the sound of breathing, especially Liu Shu, his eyes widened, he almost couldn't believe this fact, he knew that the high-speed train imported from abroad would be very high, but he didn't expect that it would be as high as this, I was used to seeing horse-drawn carriages of about 40 kilometers, and ordinary trains with a speed of less than 40 kilometers, in Liu Shu's thoughts, this train was fifty or sixty kilometers, but now, more than 4 kilometers ahead, The average speed is already more than 60 kilometers, because in about 4 minutes, more than four kilometers have been covered.

The start of the steam locomotive has always been in Liu Shu's eyes, the initial speed, the gradual acceleration from zero, at least in a minute or so, is not much speed, that is to say, in this range, the speed has exceeded 70 kilometers.

The familiar 40 kilometers become 70 kilometers, almost more than double the speed, which represents a faster speed, Baotou and the outside world are more closely connected, the future he will return to Shanxi from Baotou, maybe, a few hours will be enough.

Time passed minute by minute, less than 3 minutes, the second dispatcher stood up, Liu Shu was still immersed in shock, and the others didn't even notice, his clear and firm voice echoed in the whole room, 9:36:21, the second node was clear.

At the second node, Liu Shu was affected by the voice, and he asked with uncertainty: "Are you sure?" ”

"That's right, it's been confirmed twice!"

The world of the transmitter is separate, when they work, they only focus on the electronic signal itself, for the sake of security, under normal circumstances, the number jù will be confirmed twice, which is not conducive to secrecy, continuous similar signals, easy to be monitored or even cracked by the other party. Don't worry at the moment, this era, there is no radio era, let alone radio signal monitoring, the current play this, are some enthusiasts.

Liu Shu knew that there was no point in continuing with the dispatcher, so he turned his head to look at Yang Yuanzhao and said, "Yuanzhao, is the speed of this train so fast?" ”

Yang Yuanzhao nodded and said: "Yes, when the engine is not replaced, its average speed can exceed 120 kilometers per hour!" ”

120 kilometers, like a heavy mountain, pressed on Liu Shu's heart, the thought of the speed of the railway will be increased by 3 times than before, as if there is a temptation, the railway is different from the carriage, in addition to stopping at the station, the rest of the time, can always run, even at night, this can be achieved on other railways, in Baotou higher level of the railway can also be, thinking of a little more than 2 hours, you can rush from Taiyuan to Baotou, he has a dreamlike feeling.

In fact, the number reported by the dispatcher is similar to what he estimated, it should not be possible to be so fast before, because he instructed that the maximum speed cannot be exceeded, and now, it is obvious that Zhan Tianyou has broken through his order, so in the acceleration stage, the second section is one of the stages of the speed explosion, even if the steam locomotive starts slowly, the distance of about 8 kilometers is enough to accelerate to about eighty percent of the maximum speed, after Yang Yuanzhao's improvement of this steam engine, the acceleration performance is even more than this era, Yang Yuanzhao estimated a little, the highest should be more than 120 kilometers.

Immediately afterwards, one node after another, there was a summary of the news, the average distance of a little more than 4 kilometers, the fastest speed, and even reached 1 minute and 40 seconds, which is equivalent to saying that in this area of a little more than 4 kilometers, the average speed exceeded 150 kilometers per hour.

At this time, Liu Shu was already wooden, if the dispatcher told him that the train would fly, he would also believe it, he had seen Yang Yuanzhao do countless magical things, and there was nothing more, his wooden head, did not think about it, this speed, what would it bring to Baotou, but the traffic would definitely be a convenient mess, as long as you want to go home in the future, send a telegram to your home, leave at noon, and come back before dinner in the evening, just follow the convenience of going from home to Taiyuan.

The test has been basically completed, the train is running at the limit of high speed for a considerable period of time, more than 150 kilometers of speed, in the field of trains in this era, it is definitely in the forefront, and according to the telegram, occasionally report the state of the train, steady and plain, obviously, the state of the train is very good, at present, there are still two or three nodes to reach the end of the test, it is clear that this test, in a sense, can be said to be successfully completed.

Time passed very fast, finally, 24 minutes later, the train stopped smoothly in the station 50 kilometers away, the average speed of the entire 50 kilometers per hour, more than 125 kilometers per hour, this speed, absolutely satisfied everyone, especially Zhan Tianyou who sat on the train, the most important thing is that the number jù transmitted back over there showed that the state of the whole train was very good, high-speed driving, and there was no slightest problem, such as wheel wear, or the mechanical structure of the entire car bodyBecause of the fast speed and the failure of the control and many other problems, this is equivalent to saying that the overall operating state is very good, and this locomotive is basically qualified.

Next, it is a long wait, nodes, but is only a part of the number jù of the whole test, the number of the train passing through the entire node jù, you can calculate the average speed of the train in the previous node, there are several nodes, but the peak value can not be calculated, in this test, in each node, reasonable division of 10 areas, 400 meters of interval, there will be a watch for timing, according to this and distance, you can calculate, in more than ten seconds, or even less time of peak speedIt is not the speed of the train in time, but it is enough for them to carry out a complete, even limit, analysis of the number of trains, which is very important for a new train, and it is also the key to the actual operation of the train this time, which will determine the basic speed of the train when it runs on the Baotou Railway in the future.
